What is a hand in length measurement?

A hand is a traditional unit of length equal to exactly 4 inches or 10.16 centimeters, originally based on the breadth of a human hand.

Where is the X-unit [X] used?

The X-unit [X] was historically used in X-ray crystallography and spectroscopy to express X-ray wavelengths and atomic-scale distances.

Why would I convert hand to X-unit [X]?

Converting from hand to X-unit [X] helps compare conventional length measures like horse heights to atomic-scale measurements for scientific or historical analyses.
